I really like working in the library but there have been some extremely sketchy people recently. I have noticed the signs saying not to leave your stuff unattended. Yesterday when I was working in a study room on the 1st floor there were two men about 40s, white, dirty clothes who were just sitting on the couches and waiting for me to leave my stuff. They literally weren't doing anything but looking around. Weren't even trying to act like they were studying. I went to the bathroom and took all my stuff with me and when I got back they had left. I think it would be good to institute a policy where you have to show your badge to get into the library.
Wouldn't actually have to enforce it with everyone but these people are extremely easy to spot, so just put signs up and enforce it with them.
